Preliminary support for index format v3 by blahgeek · Pull Request #2081 · gitpython-developers/GitPython

index.version

There's this minor thing that I'm not sure if it's an issue:

Currently, the version field of IndexFile is always set to 2 after __init__. Since it's lazy loaded, it's only after its first read of entries when its version field is set correctly. Do you think we can keep it this way?
